摘要： PROBLEM TO BE SOLVED: To provide an exhaust gas turbocharger securing maintainability by easily detaching and attaching an inner casing and solving a problem of thermal expansion making design difficult and a problem of weight increase.
SOLUTION: In an axial flow exhaust gas turbocharger TC constructed to rotate a coaxial compressor by shaft output obtained by expansion of exhaust gas introduced in an axial flow turbine 20, the separate inner casing 21 and an separate outer casing 22 are integrated by bolt joining. A double structure gas inlet casing 25 in which a space formed between both of the casings 21, 22 become an exhaust gas flow pass 24 leading exhaust gas to a turbine nozzle 23 is provided. The exhaust gas flow pass 24 is provided over whole circumference in a turbine rotation direction and the inner casing 21 is made detachable in the axial direction.
